Impact Minerals records further big PGM numbers at Broken Hill

/in /by

THE DRILL SERGEANT: Impact Minerals (ASX: IPT) reported it has assayed further high grades of the rare platinum group metals rhodium, iridium, osmium and ruthenium from a high-grade 3.5 metre wide intercept of palladium, platinum, gold, copper, nickel and silver.

The results come from a recent drill hole (RHD012) conducted on the company’s Broken Hill project in New South Wales.

Samples were originally assayed by the fire assay technique with lead-collection at the Intertek laboratory in Adelaide, after which sample pulps were sent for repeat assays and assays for the rare PGM’s by the fire assay technique with nickel sulphide-collection at the Intertek laboratory in Perth.

According to Impact, the repeat assays (three in total) confirmed previously reported palladium, platinum and gold grades returning gold ranges from 10.8 grams per tonne to 14.8g/t, platinum from 10.3g/t to 12.5g/t and palladium from 280g/t to 300g/t.

Hole RHD012 has now returned:

3.5 metres at 159g/t (5.3 ounces) 6PGE+gold 2.9 per cent nickel, 2.3 per cent copper and 14.5g/t silver from 67.3m down hole (50 m below surface) where the 6PGE+gold equals 1.7g/t rhodium, 2.6g/t iridium, 2g/t osmium and 1.1g/t ruthenium, 5g/t platinum, 6g/t gold, 144g/t (4.6 ounces) palladium;

Including:
1.2m at 335.8g/t (10.8 ounces) 6PGE+gold, 7.4 per cent nickel, 1.8 per cent copper and 19g/t silver from 68.5m where the 6PGE+gold equals 4.6g/t rhodium, 7.2g/t iridium, 5.6g/t osmium and 3.1g/t ruthenium 10.4g/t platinum, 10.9g/t gold, 294g/t (9.5 ounces) palladium.

“These results, together with previously reported high grades of rare PGM’s throughout Impact’s project area are exceptional even on a global scale,” Impact Minerals said in the company’s ASX announcement.

“They indicate a potentially deep source for the parent ultramafic magmas which themselves contain evidence of having absorbed (been ‘contaminated by’) extensive amounts of the surrounding metasedimentary rocks.

“These two criteria, a deep source and contamination, are important components of models for the formation of major nickel-copper-PGM deposits and this is considered encouraging for further exploration throughout the Broken Hill project area.”
